The purpose of research - development of mathematical models, modes of study and creation of a fundamentally new structureAutomatic Frequency and Power Control systems (AFPC) of United Energy System of Ukraine, built on consumer controllers. In work presented and studied in detail a model in which the function of frequency and power-users are provided with controllable load. The proposed model is a canonical system of differential and algebraic equations, which consists of the equations describing the balance of power in the power system, the electromagnetic processes in generators, loads and controllable load, electromechanical processes regulating power generators, regulators and controllable load. In contrast to existing models of the proposed theory and give the opportunity to explore the processes in AFPC traditional regulators (generators) and in new systems AFPC consumers with fast-regulators in highly nonlinear formulation, which allows the use of real data controllers with highly nonlinear constraints and ensure adequacy of the results of calculations and actual results. With the developed model created a problem-oriented program complex, which made detailed studies of automatic control of frequency and power interconnections with fast controllable load. The first time the transient control systems with nonlinear constraints, the most effective set its laws to ensure the minimization of the extent and nature of the aperiodic transient developed dependence to determine the necessary parameters of the laws of regulation. Conducted a large number of calculations of transients in AFPC with variations as AFPC structure and the laws and the characteristics of regulators with nonlinear constraints. Investigated system AFPC traditional and proposed structures and subsequent laws regulating: proportional (P), proportional-derivative (PD), proportional-integral-derivative (PID). In this case, a wide range of variable constant inertia of regulators, and the coefficients of the proportional, integral and differential components. Studies have shown that the use of the P and PD-laws is impractical because it is inherent in major drawback - the presence of statism. Using the PID function eliminates statism and provides aperiodic nature of the transition process. Application of PID function in the structures to consumers, regulators with significant prior provides requirements for the stabilization time of frequency and power regulations of the European Union for the energy ENTSO-E. Comparison of the results showed that the main indicators AFPC with controllable load (speed, accuracy, resource, cost, etc.) are much better indicators of traditional systems AFPC. Based on multivariate calculations developed management structure frequency and power of the interconnected systems, operating with this principle of regulation. It is shown that for the energy use of the proposed structures of Ukraine repeatedly reducing the amount of capital required and the time necessary for its accession to the European Union's energy system, greatly extends the resources of regulatory units, reduces fuel consumption and emissions.
